This invention relates to improvements in a combined pedestal cabinet and heating unit, and more particularly to a pedestal cabinet for use .7 with a lavatory basin; The present application is a continuation-in-part of my application Serial No. 218,349, filed June 28, 1938. The primary purpose of thefpresent' invention is to simplify and improve the structures shown in my above- 29 the extreme cbid months, individuals have a v tendency to leave the heater on during the night' in order to keep'the bath room heated at all times. This is a source of danger as thereis a possibility of the flame being blown out and endangering $5 the occupants of the house. Furthermore, this type of heater has many aspects of a fire hazard due to a bathers tossing a towel or article of clothing on or near the gas heater.

' Like in my pending application I have by my so new improvements eliminated the disadvantages of present day bathroom heaters and I will'now describe such improvements in detail in connection with the accompanying drawings in which: Fig. 1 is a perspective view of a pedestal cabinet 35 and lavatory basin viewed from the-front end with the door of the cabinet open.

Fig. 2 is a similar view looking toward the rear of the cabinet.

Fig. 3 is a side elevation partly in vertical section and showing the manner of connecting the pipes of the lavatory basin and heater to the circulating system of the home, the section being taken on the line 3-3 of Fig. 4.

Fig. 4 is a' transverse vertical sectional view taken on the line 4-4 of Fig. 3.

' Fig. 5 is aperspective view of the heater hous- I ing or unit shown detached from the cabinet.

4 Fig. 6 is a bottom plan view of the unit shown Fig. 7 is a detail perspective view of one of the upper corners ofthe cabinet and showing the adjustable means employed in mounting the lava- (Cl. 4-1) i section of a simplified-modificationof the invention. Fig. 9 is a side elevationpf the same-partly in longitudinal vertical section- Referring first to the structures shown in Figs. 6

1 to '7 inclusive, l0 designates a cabinet made of any-suitable material and preferably of enameled sheet metal. The cabinet has supporting legs ll,

a front door opening l2, and upper rear opening I! and a lower rear opening l4. As best shown 1 in Fig. 4, the bottom of the cabinet has an opening I! for the entrance of cold air into the heating unit it.

The opening I! is normally closed by a front door I! and each side of the cabinet has a grille work or louvre section It for the discharge of hot air through the sides of the cabinet.

The unit It may be of U shape as shown in the drawings, that is provided with a hollow housing consisting of a cross portion I 9 and upwardly extending arm or flue portions 20, the latter terminating in curved top portions or hoods 2|, the

edges of which snugly engage the inner surfaces of the side walls of the cabinet, and the portions 2| functioning to direct the heated air through 2 the louvre portions 18. It will be'apparent that the unit l6 may be integral with orremovable from the cabinet iii. I

At the rear of the unit l6 thearms or fiues 20 are extended as shown at 22"so as to provide flue portions having theirdischarge ends 23 in register with the rear opening l3 of the cabinet so that the heated airwill 'not alone be discharged through the sides of the cabinet but also at the upper portion of the rear of the cabinet.

Any suitable type of heater 24 is arranged in the cross portion 19 of the housing but I prefer? ably employ a hot water radiator type heater, and hook the same up by a pipe 25a with the. pipe 25 which supplies hot water to the faucet 26 of the plumbing fixture or lavatorybasin' 21. A twoway cock 28 is interposed in the piping for the purpose of cutting the radiator either into or out of the system without disturbing the flow or circulation of hot water to the faucet 26. Such piping may be arranged as disclosed in my previous application.

Due to the U-shaped structure of the unit It, there is a space 2!I between'the flues 20 for the accommodation of the drain pipev 30 and the twoway valve 28. v I

I The fixture or basin 21 may be of conventional type and in accordance with the present invention it is supported directly by the cabinet. For

this purpose each one of the upper corners of 5 the cabinet is provided (Fig. '1) with a threaded block 3| through which passes a vertically disposed screw 32', the basin resting directly on such sides of the block 3| and they engage the inner surface of the apron or skirt ll or the basin. At this point it will be noted that the lower edge of such skirt, at the sides or the cabinet, is positioned above the louvre sections l8. It will be understood that the basin can be made integral with the cabinet if so desired. 1 i

In use, if the valve 28 is set to cause hot water to travel through the radiator 24, it will be ob-- vious that cold air will enter the bottom of the unit It, be heated and then will be discharged through the louvre structures I. and throughthe discharge ends 23 of the fiues at the rear of the cabinet.

As the outer walls 35 oi. the heater are spaced from the side walls of the cabinet, this structure will function in a measure to insulate the cabinet and'thereby prevent the burning of any one coming in contact with the exterior of the cabinet. The hoods 2| also function as shields to prevent the heated air from heating the basin 2?; in other words, to insulate the basin.

In the embodiment of the invention illustrated in Figs. 8 and 9, the lavatory basin 40 may be supported in the same manner, as shown in Figs. 4 and 7, but I eliminate the housing unit It entirely and thereby reduce the cost of the structureand simplify the same. In this modification, the cabinet 40a is provided with a horizontal :partition M which is positioned below the basin 40 and functions with the walls and bottom of the cabinet to form a heater compartment 42 which has louvre sections 43 and 44 arranged respectively in the sides and rear 01' the cabinet below the partition ll. Here also the cabinet may have a doorway l5 closed by hinged door 48.

Below the heater 41, which is positioned in the compartment 42, the bottom of the cabinet has an opening 48 for the entrance of the air to be heated, and of course, after the air is heated it will bi discharged through the louvre seqtions l3 and l Obviously my improvements may be used with other types of plumbing fixtures such as kitchen sinks, wash tubs orthe like. I l

While I have disclosed what I now consider to be preferred embodiments of the invention in such manner that they may be readily understood by those skilled in the art, I am aware that changes may be made in the details without departing from the spirit oi the invention as expressed in the claims.
